package main
// domainGrouper groups by domain.
// but it keeps the other fields.
// for example: it returns pages as well, but you shouldn't use them.
// exercise: write a function that erases superfluous data.

return r.domain
}
func pageGrouper(r result) string {
return r.domain + r.page
}
// groupBy allocates map unnecessarily

// return randomStrings()
